 WHEREAS, Customer desires to obtain from MCI the SS7 DIRECT
Service described herein;

 NOW, THEREFORE, in consideration of the mutual covenants and agreements in this Agreement, the Parties agree as follows: 
  
 1. Service. During the Service Term of the Agreement, MCI will
provide “SS7 DIRECT Service” which is Signaling System 7 (“SS7”) signaling between Customer’s SS7 network and MCI’s SS7 network. SS7 DIRECT Service supports signaling for dedicated long distance traffic
between switches and/or Signaling Transport Points (“STPs”) owned and operated (or leased and operated) by Customer and its Parent Company (“Customer Locations”) and MCI’s signaling network. Customer’s
ability to receive and use SS7 DIRECT Service shall be based on MCI’s interconnection availability as determined by the successful installation and testing of MCI’s links. MCI, at its sole discretion, reserves the right to deny SS7 DIRECT
Service to any requested Customer location. 
  
 2. Technical
Requirements. Customer’s network shall conform in all material respects to MCI SS7 Network Interface specifications for interexchange carriers specifications #005-0050-01, D-ES revision 1.1, July 16, 1990 and Bellcore specification TR
394. Any changes in Customer’s switch or STP hardware or software must be compatible with the Bellcore TR 394 SS7 network technical specifications, and MCI must be given sufficient advance written, notice thereof to provide MCI reasonable time
to adjust its own facilities and services to correspond to such change; provided that such notice shall at no time be less than five (5) business days prior to the effective date of such change. 
  
 3. Interconnection and Testing. 
  
 (i) SS7 DIRECT Service will support all long distance
originating or terminating traffic on dedicated facilities from or to Customer Locations, utilizing point codes (“Point Codes”) owned or leased and operated by Customer. Customer hereby represents that all 

  

 1 









 
point codes to be provided to MCI will be owned or leased and operated by Customer. Upon execution of this Attachment, Customer will provide MCI with a list
of cities, CLLIs and Point Codes owned or leased and operated by Customer to be connected into the MCI network which list may be updated from time to time upon notice to MCI as Customer adds switches to its network. MCI reserves the right to review
the Point Codes to ensure they belong to Customer. 
  
 (ii) Customer understands and agrees that SS7 DIRECT Service shall not be used to support signaling for local traffic and MCI will not support TCAP messages. 
  
 (iii) MCI only provides SS7 DIRECT Service to Customer’s Location(s). Customer acknowledges and agrees
that the following activities are prohibited (i) the resell of SS7 DIRECT Service, (ii) arrangements where STP’s and/or switches that are not owned and operated (or leased and operated) by Customer and its Parent Company pass SS7 messages to
MCI’s signaling network and (iii) Customer shall signal only [*] 
  
 (iv) MCI retains the right to immediately terminate Customer’s SS7 DIRECT Service for failure to comply with this Section 3. 
  
 4. Operation and Maintenance. MCI will operate and maintain each MCI STP seven (7) days per week, twenty-four
(24) hours per day. In the event of an outage of an MCI STP, MCI will respond in accordance with MCI’s policies and practices in effect at the time of the outage, as determined by the MCI location affected by any such outage. In the event of
any interruption of SS7 DIRECT Service, MCI. shall, upon the earlier of (i) MCI becoming aware of such interruption, or (ii) delivery of notice thereof by Customer, immediately commence and diligently pursue the restoration of SS7 DIRECT Service in
compliance with priorities established under federal laws and regulations. Customer agrees to cooperate with MCI in all restoration efforts. 
  
 5. Exchange of Technical Data: Forecasts. Customer and MCI shall exchange all necessary Point Code and other technical information as is
necessary to establish and maintain the SS7 DIRECT Service. Additionally, within thirty (30) days following the execution of this Attachment, Customer will provide MCI with a forecast of Customer’s anticipated long distance traffic and
link/port requirements for SS7 DIRECT Service for the first six (6) months of Customer’s use of SS7 DIRECT Service (the “6-Month Forecast”). Customer shall review and update the 6-Month Forecast on a regular basis, but no later than
six months following the issuance of the preceding 6-Month Forecast. Customer shall immediately notify MCI if Customer has reason to believe Customer’s link/port requirement or anticipated signaling will materially change. MCI shall not be
responsible for service interruption, degradation in the quality or the service or any other service defect that may result from Customer exceeding the forecast levels, failing to provide a complete or timely forecast, or failing to provide MCI with
advance notice of a material change to the projections contained in Customer’s 6-Month Forecast(s).

 6. Interconnect Circuits. 
  
 (i) If (a) Customer uses a switch for SS7 signaling, MCI shall install a minimum of two (2) 56kbps Digital
Data Service (DDS) circuits connecting MCI’s STPs and Customer’s location(s), as specified by Customer (“Links”), and (b) Customer uses STPs for SS7 signaling, MCI shall install a minimum of four (4) 56kbps Digital Data Service
(DDS) circuits connecting MCI’s STPs and Customer’s locations, as specified by Customer (“Links”). Customer shall utilize MCI’s 56kbps DDS circuits from MCI’s STPs to MCI’s POPs. Local access between
Customer’s locations and MCI’s POPs shall be ordered on a DS-1 circuit. The other channels of the DS-1 may be used for other services provided by MCI. MCI will provide two-way link diversity if Customer uses a switch for SS7 signaling (and
three-way link diversity if Customer uses STPs for SS7 signaling) throughout the MCI signaling network (including local access) where such diversity is commercially reasonably possible. Customer shall reimburse MCI for all additional charges
incurred by MCI from a LEC or third party access provider to meet such diversity requirements. Any exceptions to tin’s requirement must be prior approved by MCI’s SS7 Engineering Department. 
  
 (ii) In the event Customer orders its own local access for
SS7 DIRECT Service, the local access must meet all of MCI’s requirements for entrance and diversity into MCI’s SS7 network. Further, in such case, Customer is responsible for maintaining its own local access and MCI will have no liability
in connection therewith, MCI will not contact the local access provider directly, however, upon request, MCI agrees to assist the local access provider in testing and restoring local access.
